Newport Beach Warns Public as Coastal Flooding Hits Peninsula

Coastal flooding has inundated streets and properties on Balboa Peninsula in Newport Beach, California, prompting city officials to urge residents and visitors to avoid the affected community as storm conditions and elevated tides increase flood risks. Emergency crews are responding to impacted areas, while the National Weather Service has issued a coastal flooding advisory that remains in effect through Tuesday. The flooding has affected local streets and private properties, although the full extent of the damage has not yet been determined.

Newport Beach officials have advised the public to stay away from Balboa Peninsula while crews address conditions in affected areas. Aerial footage from the peninsula showed people wading through flooded sidewalks and streets. Some pedestrians encountered water reaching their knees, while several vehicles appeared nearly submerged.

The National Weather Service warned that high tides would remain above normal across the affected coastline. South-facing beaches are expected to face particularly elevated water levels, including areas of Newport, Long Beach, Dana Point, and Laguna Beach.

Flooding risks are expected to peak on Sunday, when tides could reach 1 to 1 ½ feet above astronomical tide predictions, according to the National Weather Service. The elevated tides, combined with recent storm conditions, are contributing to the coastal flooding threat. Newport Beach officials issued a public safety warning urging motorists to avoid flooded roadways and follow instructions from emergency personnel.

"Do not drive through flooded streets. Use alternate routes, exercise caution, and follow directions from public safety personnel," the city of Newport Beach said in a statement. City crews remain engaged in responding to affected areas. Officials have not yet established the total extent of property damage caused by the flooding.
